I bought Vostro 5470 with core i7 and facing different problems and one of the major one is error in keyboard (number 9) that results in writing of 9 on its own and the computer is held as long as the number is being written in its own. Sometimes it stops autmatically and then pointer starts working.

If I want to write something or want to search number 9 is written itself and it continues ad such.

Facing immense problem due to this.. Probably I have to replace whole keyboard but i am affraid if the priblem will still prevail.
